Reduced-Intensity Hematopoietic Stem Cell Transplant for High Risk Lysosomal and Peroxisomal Disorders

Treatment of High Risk, Inherited Lysosomal and Peroxisomal Disorders by Reduced-Intensity Hematopoietic Cell Transplantation and Low-Dose Total Body Irradiation With Marrow Boosting by Volumetric-Modulated Arc Therapy (VMAT)

This study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) in patients with high-risk lysosomal and peroxisomal disorders using a novel conditioning regimen for hematopoietic cell transplantation (HCT). After a reduced-intensity conditioning regimen using volumetric-modulated arc therapy (VMAT)-delivered low-dose total body irradiation (TBI) with highly conformal marrow boosting, patients will be transplanted using either a related or unrelated allograft. The cell source may be marrow, peripheral blood or cord blood based on donor availability.

Study Overview

Detailed Description

The conditioning regimen consists of alemtuzumab (Campath-1H), clofarabine, melphalan, and VMAT-delivered low-dose TBI with boosted marrow irradiation. Additional graft-versus-host disease prophylaxis consists of mycophenolate mofetil and cyclosporine.

Description

Inclusion Criteria:

  • Adrenoleukodystrophy (ALD): Patients from 0-55 years of age diagnosed with ALD as determined by very long chain fatty acid testing will be eligible for this protocol if they have evidence of cerebral or cerebellar disease based on MRI testing,
  • Metachromatic Leukodystrophy (MLD): Patients from 0-55 years of age diagnosed with MLD as determined by arylsulfatase A activity.
  • Globoid Cell Leukodystrophy (GLD): Patients from 0-55 years of age diagnosed with GLD as determined by galactocerebrosidase activity will be eligible for this protocol
  • Wolman's disease, GM1 gangliosidosis, Tay Sachs disease, Sanfilippo syndrome, Sandhoff disease or other inherited metabolic diseases including but not limited to I-cell disease (mucolipidosis II): Patients who are determined to be sufficiently advanced or high risk based on the following reasons:

    • Symptomatic disease, as based on neurologic examination or evidence of deterioration based on subsequent neuropsychologic evaluations.
    • Evidence of an expected poor outcome based on genetic testing or a prior family history of aggressive disease.
    • Other metabolic disorders, including but not limited to I-cell disease, that are deemed to be high-risk for a poor outcome with a standard transplant regimen due to anticipated toxicity based on experience gained at the University of Minnesota or other centers.
  • Donor Availability

    • Transplantation using sufficiently matched related donors (such as matched siblings) or unrelated donors will be considered. Both granulocyte-colony stimulating factor (G-CSF) stimulated peripheral blood grafts and bone marrow grafts will be considered, although bone marrow will be the priority.
    • Cord blood grafts, both related and unrelated, are also eligible. As this protocol will use a reduced intensity regimen, this protocol will use the current recommendations of the University of Minnesota for choosing cord blood grafts. If a single cord blood unit cell dose is insufficient, double cord transplantation should be considered if sufficiently matched cord blood units are available. The priority of choosing cord blood donors is based on the current institutional recommendations.
    • Exclusion of Metabolic Disorder Carrier Status from related donor and unrelated cord blood grafts as appropriate for primary disease.
  • Adequate Organ Function - Measured within 30 days of study enrollment
  • Signed consent

Exclusion Criteria:

  • Inability to receive total body irradiation (TBI) with marrow boosting per protocol guidelines as determined by the Radiation Oncologist
  • Pregnant - Menstruating females must have a negative serum pregnancy test within 14 days of treatment start.
  • Advanced Disease Exclusion: Following evaluation, if a consensus of the members of the Inherited Metabolic and Storage Disease Program is that a patient is too advanced to benefit in a measurable and meaningful way from transplant, this will be communicated to the family, and transplant will not be offered.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intent-To-Treat Patients
Patients with high-risk lysosomal and peroxisomal disorders treated with preparative regimen (Campath-1H 0.3 mg/kg intravenous (IV) on days -12 through -8, clofarabine 40 mg/m^2 IV on days -9 through -5, melphalan 140 mg/m^2 IV on day -4 and Total Body Irradiation with Marrow Boosting [ first dose of 200 cGy single dose; 5 doses of 160cGy for marrow boosting - 1000cGy cumulative exposure] by Volumetric-Modulated Arc Therapy [VMAT] on days -3 through -1). Hematopoietic stem cell transplantation will be infused on Day 0. Post-transplant immunosuppression to follow: Mycophenolate mofetil (MMF) begin day -3 and continue to day +30 or 7 days after engraftment, whichever is later; Cyclosporine A (CsA) begin day -3 and then taper at day +100 if related donor, day +180 for unrelated donor.
A daily dose of 0.3 mg/kg IV over 2 hours will be administered on days - 12, -11, -10, -9, and -8.
Other Names:
  • alemtuzumab-1H

A daily dose of 40 mg/m2 will be administered IV over 2 hours on days -9,

-8, -7, -6, and -5.

Other Names:
  • Clolar
A single dose of 140 mg/m2 will be given IV on day -4 over 15 minutes.
Other Names:
  • Alkeran
  1. Dose to total body 200 cGy in single dose
  2. Dose to bone marrow of the following bones 800 cGy in 5 divided daily fractions (160 cGy x 5 doses ). Treated with up to 3 abutting VMAT photon arcs from top of head to maximum inferior border.

Patients will be transplanted using either a related or unrelated allograft. The cell source may be marrow, peripheral blood or cord blood based on donor availability.
Patients will receive CsA therapy beginning on day -3. Dosing of CsA will be 2.5 mg/kg/dose IV; if the recipient body weight is <40 kg, dosing will be 3 times daily, and if > 40 kg, twice daily. An attempt will be made to maintain a trough cyclosporine level of 200 mg/L to 400 mg/L.
Other Names:
